JUNCTION 0R TERMINAL BOX.

'Specification'of Letters Patent.

Patented Apr. 25, 1911.

Application filed June 8, 191.0. Serial No. 565,678.

To all whom it may concern:

Be it known that I, LEO GUDEMAN, citizen of the United States ofAmerica, residing at New York city, New York, have in vented certain newand useful Improvements in Junction or Terminal Boxes, of which thefollowing is a specification.

My invention relates to an improved form of junction or terminal box forelectrical equipments.

The primary object of the invention'is to provide a portable junctionbox, which owing to the simplicity of the organization of itsconstituent parts may be cheaply manugactured and is not likely to getout of or- A further object is to so construct the box that it may bemade capable of receiving any desired number of plugs or other terminalsused for completing an electric circuit.

Although the invention is adapted for use in any connection wherejunction boxes are required, it is of particular advantage ininstallations where a portable junction box is convenient, for examplein stringing lamps on Christmas tree outfits and the like.

The invention is illustratively exemplified,

in the accompanying drawing, wherein- Figure 1 is an elevational viewpartly in section of a junction box embodying my invention and having anumber of plugs inserted therein; Fig. 2 is a side elevational viewthereof; Fig. 3 is an end view thereof; Fig. 4 is a top plan view of ametallic conducting block; Fig. 5 is a side elevational view of thesleeve of a terminal plug; Figs. 6, 7 and 8 are detail views of theplug.

Referring by reference characters to the drawing 15 designates a sleeve,preferably cylindrical in form, and made of a material such ascompressed fiber or the like, the

sleeve being designed to inclose blocks 16 of metallic conductingmaterial such as copper. There are preferably two such blocks employed,and the are-separated by a non-conducting layer 1% consisting bypreference of parafiin. In the form of invention shown in Figs. 1 and 2,the exposed surface of each copper block is covered with packedinsulation 18 over which I place a layer of pitch 19 or the like.-Passing through the pitch and insulation are the incoming wire cable 20and the out-going wire cable 21, each thereof having its terminals 20bare and secured to the copper blocks as by soldering or the like. Thesleeve 15has a plurality of perfora tions 22 in line with passages 23 inthe copper blocks to receive the split ends 24 of plugs which havesleeves 25 in which the ends of wire cables 26 are suitably secured.When the plugs are forced into the openings in the sleeve 15 and blocks16 a circuit is.

coupled through the plug, the copper block the sleeve, then placing theparaffin layer 17 in position, then driving in the other copper block,attaching the terminals 20 to the blocks and finally filling in theinsulation 18 and running the pitch layer 19 over the exposed insulationsurface.

It will be understood that I may, if desired, increase the number ofcopper blocks for each junction box, and may also make the latter of anydiameter to provide room for a suitable number of openings to receivethe plugs 2425.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. A junction box comprising the combinationwith an exterior sleeve provided with suitable plug openings, of aplurality of metallic conducting blocks superposed in the longitudinaldirection of the sleeve and having passages in line with the openings inthe sleeve.

2. A junction box comprising the combination'with an exterior fibersleeve provided with suitable plug openings, of a plurality of copperblocks, said blocks being superposed in the longitudinal direction ofsaid sleeve and being provided with passagesin terial between sa dblocks, and insulating material covering the exposed surfaces of saidblocks.- I
